Is my JMAP configuration correct? Any howto notes available?

Hi all,

First time posting here.

I would like to configure a small mail server with JMAP via Cyrus. I=20
have been intrigued by JMAP and been wanting to try it out for quite=20
some time.

As it is, I have been struggling a bit to set it up. The documentation=20
seems a bit sparse, and I am not 100% sure I got it all configured=20
correctly now. I test with `curl` and `aerc`, and things seem to be working.

I will attach my current non-default configuration below. Any=20
recommendations / improvements / pointing out of errors etc are most=20
welcome!
This is on Debian 13, binaries from Debian, with Cyrus 3.10.2.

Besides, it would be nice to see a write-up of a somewhat "normal" small=20
mail server with JMAP support. I have looked for a long time and cannot=20
seem to find such a thing. I even attempted to use AI to guide me=20
through the different error messages (I went and complicated things by=20
putting a reverse proxy in front of Cyrus - not even sure if this is=20
considered good practice?), but it was painful (I suppose because not=20
much info is available on the Internet).

If anyone knows of, or has a write-up they would like to share, please=20
do! I think it would be amazing if we could encourage more people to use=20
Cyrus and JMAP! Once I got everything running and working correctly, I=20
would be happy to write a blog post about the configuration as well.

Many thanks for your time!

Kind regards,
